profile picture pupdate: strong consensus for: dog, but more professional. Introducing my new profile pic:

NEW | The world installed a record 814 GW of solar and wind capacity in 2025 ☀️⚡️ That's over 1,000 TWh of electricity generation per year... ...enough to displace nearly twice Qatar's annual LNG export volume in gas generation 🔥❌ Fossil fuels crisis? Wind and solar deliver.

On The Climate Brink, my last post talks about the runaway greenhouse effect and whether we should worry about it. No spoilers here, you'll have to read it to find out!

this is what actual national suicide looks like btw

If you are interested in running for President or Secretary of the AGU's Global Environmental Change section, email me (adessler at tamu dot edu) and attach your CV. We are looking for candidates and the deadline is coming up soon.

@IBergwiesel OK, trying again since the last link didn’t work … I asked chatGPT to give me a peer review and it concluded the same thing: reject drive.google.com/file/d/1EG6HYP…

I had Claude read Cohler et al (2026) and it turned into a straight-up massacre. claude.ai/public/artifac…

As I wrote yesterday, these are actually linked. As we spend less on fossil fuels, we can also spend less on national defense. This is yet another subsidy for fossil fuels. theclimatebrink.com/p/the-war-in-i…

On The Climate Brink, @hausfath.bsky.social writes about the trends of spending on clean energy vs. national defense: When will clean energy spending exceed military spending?

On The Climate Brink, my latest post is on what the war in Iran tells us about the hidden costs of fossil fuels

On The Climate Brink, an obituary for the DOE Climate Working Group report theclimatebrink.com/p/obituary-the…

An obituary for the short-lived DOE Climate Working Group, from @AndrewDessler over at The Climate Brink. It arose with a bang and died with a footnote in the EPA's endangerment finding repeal.

As a rare climate scientist working in Silicon Valley, I've been drinking from the AI firehose a lot more than my peers. I thought it would be helpful to lay out my experiences of both the promise and pitfalls of using AI to accelerate scientific research.

I know that AI is controversial in some corners, but I think this is a great description of how many scientists (particularly younger ones) are using it. theclimatebrink.com/p/the-ai-augme…

@ryanhanrahan @danrothenberg @mattlanza Interesting. So the idea is that a YouTuber will generate a sensational forecast in order to drive clicks. That seems plausible. It also seems like that would work once but not consistently.

@danrothenberg @AndrewDessler @mattlanza You'll also see these engagement farms just pumping out a lot of really compelling content. It will be virtually impossible to distinguish between reality and garbage. The social media companies clearly don't care about this.

The consternation around this mystifies me. We already know that having multiple ways to receive warnings is a vital component for improving public safety. I've used caller services for two decades offered by my county, towns, and private companies - on top of WEA and a wx radio.

@danrothenberg @ryanhanrahan @mattlanza … (who isn’t tweaking the inputs) your forecast will be dismissed … ??

@danrothenberg @ryanhanrahan @mattlanza Certainly I understand that you can tweak the inputs to any model to get an output that you want. But I presume the goal would be to convince everyone that the desired event is going to happen but if your forecast is different than everyone else’s …
